运行对 DataProvider 中的每个数据集按顺序进行的一组测试

Question

我需要运行在来自 DataProvider 的每个数据之前进行一些测试。
例如，在下面的示例 class 中，我需要运行 someStart 测试 4 次（在每个数据之前），该怎么做？

public class Poligon {

    @Test()
    public void someStart(){
        System.out.println("Start");
    }

    @DataProvider
    public Object[][] getData() {
        return new Object[][]{{"a",1},{"c",2},{"d",4},{"x",0}};
    }

    @Parameters({"p","n"})
    @Test(dataProvider = "getData", dependsOnMethods = "someStart")
    public void x(String p, int n){
        String[] a = {"a","b","c","d"};
        int i = 0;
        while( i < a.length && !a[i].equals(p)) i++;
        i = (i < a.length)? i + 1 : 0;
        System.out.println(p + ": " + i);
        Assert.assertEquals(i, n);
    }

    @Test(dependsOnMethods = "x", alwaysRun = true)
    public void someEnd(){
        System.out.println("End");
    }

}

编辑

我需要运行这样的：

Test01 group1
Test02 group1
Test03 group1
DataProvider
Test11 group2 with 1st data set
Test12 group2 with 1st data set
Test13 group2 with 1st data set
Test11 group2 with 2nd data set
Test12 group2 with 2nd data set
Test13 group2 with 2nd data set
...
Test11 group2 with xth data set
Test12 group2 with xth data set
Test13 group2 with xth data set
Test21 group3
Test22 group3
Test23 group3

Answer 1

我在这个站点找到了答案：www.journaldev.com and howtodoinjava.com。但这不是我真正需要的。我无法运行多组具有不同 Factory 且没有按预期顺序进行的测试。

第 1 次：添加了 class 和 Factory
2zh: 在测试中添加局部变量和构造函数 class

工厂class:

import org.testng.annotations.DataProvider;
import org.testng.annotations.Factory;
import org.testng.annotations.Test;

@Test()
public class Poligon2 {

    @Factory(dataProvider = "class-data-provider")
    public Object[] getTestClasses(String s, int n) {
        Object[] tests = new Object[1];
        tests[0] = new Poligon(s, n);
        return tests;
    }

    @DataProvider(name = "class-data-provider")
    public Object[][] getData() {
        return new Object[][]{{"a", 1}, {"c", 3}, {"d", 4}, {"x", 0}};
    }
}

测试class：

import org.testng.Assert;
import org.testng.annotations.*;

public class Poligon {
    final String p;
    final int n;
    int run = 0;
    static int instance = 0;
    final int current_instance;
    static int globalrun = 0;

    public Poligon(String p, int n){
        this.p = p;
        this.n = n;
        instance++;
        current_instance = instance;
    }

    @Test()
    public void someStart(){
        System.out.println("Start");
        System.out.println(String.format("Instance: %d; Instance run: %d; Global run %d.", current_instance, run++, globalrun++));
    }

    @Test(dependsOnMethods = "someStart")
    public void x(){
        String[] a = {"a","b","c","d"};
        int i = 0;
        while( i < a.length && !a[i].equals(p)) i++;
        i = (i < a.length)? i + 1 : 0;
        System.out.println(p + ": " + i);
        System.out.println(String.format("Instance: %d; Instance run: %d; Global run %d.", current_instance, run++, globalrun++));
        Assert.assertEquals(i, n);
    }

    @Test(dependsOnMethods = "x", alwaysRun = true)
    public void someEnd(){
        System.out.println("End");
        System.out.println(String.format("Instance: %d; Instance run: %d; Global run %d.", current_instance, run++, globalrun++));
    }
}

我得到了预期的结果（运行使用当前数据集进行测试）：

Start
Instance: 2; Instance run: 0; Global run 0.

Start
Instance: 4; Instance run: 0; Global run 1.

Start
Instance: 1; Instance run: 0; Global run 2.

Start
Instance: 3; Instance run: 0; Global run 3.

c: 3
Instance: 2; Instance run: 1; Global run 4.

x: 0
Instance: 4; Instance run: 1; Global run 5.

a: 1
Instance: 1; Instance run: 1; Global run 6.

d: 4
Instance: 3; Instance run: 1; Global run 7.

End
Instance: 2; Instance run: 2; Global run 8.

End
Instance: 4; Instance run: 2; Global run 9.

End
Instance: 1; Instance run: 2; Global run 10.

End
Instance: 3; Instance run: 2; Global run 11.
